Resumen:
Double ionization of He by impact of multiply charged ions is studied. Perturbative and nonperturbative regimes are analysed discriminating the influence of post-collisional effects. A simple exponential approximation, based on CDW-EIS single ionization cross sections and Bohr and Linhard predictions of the electron release distance, is shown to give an adequate description of existing experimental data.
